I need a modal dialog to open ontop of an tinyMCE editor and other jQuerified items. I followed the jquery site but its not modal, I can still change and access the rest of the page.

$('#sureDelete').dialog({
                    modal: true,
                    buttons: {
                        "Yes": function(){
                            $('li#'+$id).remove();
                        },
                        "No":function(){
                        }
                    },
                    draggable: false
        });
<div id="dialogs">

<div id="sureDelete">Are you sure you want to delete this page?</div> </div>
